The production of latexes stabilized by solid particles, so‐called Pickering stabilizers, has attracted considerable attention due to its benefits, including the enhanced mechanical properties of the polymer films. Clays for instance were found to enhance particle stabilization in emulsion polymerization, in a comparable way to conventional surfactants. Their concentration thus determines the polymer particles size and number, and consequently the reaction rate. In this work, we investigate the impact of the presence of such rigid and big platelets at the polymer particle's surface on radical exchange between the aqueous phase and the polymer particles. It was found for the system underhand that the average number of radicals per particle ( ) was independent of the stabilizer layer. Therefore, a radical capture model independent of the clay concentration could be used to simulate reactions involving different clay concentrations and predict the evolution of the monomer conversion, particle size, and . © 2018 American Institute of Chemical Engineers AIChE J, 64: 2612–2624, 2018

Pickering稳定对乳液聚合中自由基进入的影响

由固体颗粒稳定的乳胶的生产，即所谓的皮克林稳定剂，由于其优点，包括增强了聚合物薄膜的机械性能，因此引起了相当大的关注。例如，发现粘土以与常规表面活性剂相当的方式增强了乳液聚合中的颗粒稳定性。因此，它们的浓度决定了聚合物颗粒的大小和数量，并因此决定了反应速率。在这项工作中，我们研究了在聚合物颗粒表面上存在此类刚性大片血小板对水相与聚合物颗粒之间自由基交换的影响。对于下面的系统，发现每个粒子的平均自由基数（ ）独立于稳定剂层。因此，独立于粘土浓度的自由基捕获模型可用于模拟涉及不同粘土浓度的反应，并预测单体转化率，粒径和粒径的演变。©2018美国化学工程师学会AIChE J，64：2612–2624，2018
